Rotor simulation calculations made in connection with rotor tests in the DNW (German/Dutch windtunnel), using the test facilities ROTEST (Rotor Test Stand) and ROTOS (Rotor On String), are presented. The models describing the induced velocities at the rotor blades influenced rotor performance and rotor dynamics, by affecting the aerodynamic loads. The calculations were made using an incompressible panel method and the results were dependent on the rotor shaft tilt and on tunnel speed. It appeared necessary to have the induced flow of the test stands included in rotor simulation at tunnel speed higher than about 30 m/s, whereas the self induced velocities were more dominant at lower speed.
